How to remove a repository? [duplicate]

  • 772

Please let me know how to remove certain repositories in Ubuntu 11.04. I am getting the following errors while updating.

sudo apt-get update

Err http://ppa.launchpad.net natty/main Sources                                   
  404  Not Found
Err http://ppa.launchpad.net natty/main i386 Packages                             
  404  Not Found
......

E: Some index files failed to download. They have been ignored, or old ones used instead.

  1. Or from the terminal -

    sudo add-apt-repository -r ppa:<ppa to remove>

    Or, edit the /etc/apt/sources.list to find your ppa there, and remove from there manually (or automatically).

    Or, remove the ppa file from /etc/apt/sources.list.d in newer versions of Ubuntu.

    You can easily remove software repositories from the "Software & Updates"

    • Open "Software & Updates"

    enter image description here

    • Select tab "Other Software"

    enter image description here

    From the "Other Software" tab you can add or remove repositories.

  3. Using PPA Purge:

    ppa-purge can remove a PPA and downgrade all the packages you've installed from that PPA to the newest version in your other repositories. This is the cleaner way of removing repos.

    sudo apt-get install ppa-purge

    via:WebUpd8

    If you know the PPA address:

    sudo ppa-purge ppa:<the PPA to purge>

    Example:

    sudo ppa-purge ppa:fcitx-team/nightly

    If you don't know the PPA address:

    You can also purge repositories that don't have the address in the correct format yet, by changing it. Change it from:

    https://<ppa_host>/<ppa_owner>/<ppa_name>

    to

    sudo ppa-purge -s <ppa_host> ppa:<ppa_owner>/<ppa_name>

    Example: If you want to remove WineHQ repo.

    Find the correct file:

    ls -al /etc/apt/sources.list.d/

    Get the address from that file:

    cat /etc/apt/sources.list.d/dl_winehq_org_wine_builds_ubuntu.list

    Change the address from:

    deb https://dl.winehq.org/wine-builds/ubuntu/ bionic main

    to

    sudo ppa-purge -s dl.winehq.org ppa:wine-builds/ubuntu

    You can find a bit more info using man ppa-purge.

    Via GUI:

    Or you can go to Software Sources on the Ubuntu Software Center Edit menu, enter your password, go to the Other tab, look for the PPA you wan to remove, click remove and close, it will ask you to update the repos and done.
